Materials for pipelines in acidic environmental conditions
Thread Content
Oil and gas transmission pipelines contain H2S at levels of around 1,000 ppm. What materials are generally used today? Standard SY0599-2006 \"Requirements for metallic materials to resist sulfide stress cracking and stress corrosion cracking in natural gas surface facilities\" does not specify the use of GB8163; should 20# steel still be used, or should another standard be adopted?
Ultra-low carbon austenitic stainless steel or duplex stainless steel can be used with some success, but ordinary carbon steel is not resistant to stress corrosion in environments rich in hydrogen sulfide.
